For best results, a pH meter should be calibrated between pH 7.00 and pH 10.00 if you intend to test alkaline solutions; and calibrated between pH 7.00 and pH 4.01 if you intend to test acidic solutions.
WARNING: Reusing pH buffer solutions can result in contamination that will affect the accuracy of your pH calibration and subsequent measurements.
